Trigalight Tritium Vial, Tube, Capsule Glow in the dark lamp Lights

These tritium trig are the best. I've other makes and sizes which all need charging and eventually dwindle through the hours. Some better than others. These, however, need no charging at all and stay bright through the darkness. Their radioactive luminescence is absolutely amazing right out of the packaging. I think they are worth the money. These could possibly be what are used in high end watches. I bought 2 months ago, just received 3 more, and will order more soon for further projects. They are that good. Better than anything else I've used. Take note of dimensions. They are tiny powerhouses.

A lot brighter than expected, especially with night adjusted vision.I purchased a range of colours and green is by far the brightest, however that's not to say the others are dim! The output goes green 100%, yellow 80%, white 60%, ice-blue 60%, orange 40%, pink 40%, purple 30%, red 20%, blue 15%. Comparing the red to the green I would say the output seems more than 20% but the main difference is there is less "glare" and is more of a soft glow.Overall very happy with the vials, they're good quality for a good price.

I bought this for my partner to mount on the side of a toilet door so she can see if it's open or closed at night without turning a light on. For this purpose, it works perfectly. It can be seen from several meters away.

I looked at the picture and bought what I thought was five vials. All I got was one.

Have bought a bunch of these in green, orange and red. Green are obviously the brightest but I (like another reviewer) just wanted them to indicate where things are at night in a dark room and the green is overkill for that. Now I can see where the bedside table, the top of the stairs and the bathroom door are without turning on the lights.The only obvious thing that seems like it's worth an extra mention is that they are *glass* vials, so they're not going to be suitable for putting on anything that gets bashed about unless you're going to put them in some sort of housing.

Nice but would have been better if you got more than 1 rod

These are pretty expensive but obviously a high quality product. Clear bright glow in the dark. I've not quite worked out what I need them for yet, but I can't wait to come up with the project.

Glow doesn't last long and really small
